TOBACCO PIPE.

Application filed April 16, 19525.

To all whom it may concern:

Be it known that I, XVILLIAM NALLAon I-lnsson, a subject of the King of Great Britain, and resident of the city of Toronto, county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Tobacco Pipes, as described in the following specification and illustrated in the accompanying drawings, that form part of the same.

T he principal objects of the invention are to eliminate many of the disagreeable features incident to smoking, and to provide a pipe, cigar or cigarette holder which may be kept in a thoroughly sanitary condition.

The principal features of the invention consist in the novel construction and arrangement of an extension stem from the mouth-piece which will maintain a thoroughly tight joint between the stem and the bowl sothat moisture cannot get around the exterior of the stem and a clear passage will be maintained from the bowl to the mouth-piece.

In the accompanying drawings, Figure 1 is a sectional perspective view of a pipe showing one form of my improved extension stem.

Figure 2 is a similar view showing a slight modification of structure.

Figure 3 is a similar sectional view showing a further modification of the metal stem.

Figure 4 shows a still further modified structure.

The most undesirable feature about pipe smoking or the use of cigar or cigarette holders is that moisture, ashes and tobacco collect in pockets in the stem between the mouth-piece and the bowl and such collections are extremely undesirable.

Pipes having metallic tubular stems of various forms have been devised, but the present invention contemplates maintaining a continuous passage from the bowl to the mouth-piece without pockets and in which leakage of moisture from the bowl around the stem will be absolutely avoided.

The invention may be applied in various forms. In the construction illustrated in Figure 1, the bowl shank or stem 1 is bored longitudinally with an orifice 2 which terminates in a shoulder 8 arranged close to the bowl 4.

A small opening 5 of a suitable size to Serial No. 23,709.

allow the smoke to pass therethrough is arranged in central alignment with the orilice 2.

The outer end 6 of the orifice 2 is threaded with a thread of greater diameter than the orifice The mouth-piece 7 is bored iongitiulinally to receive the metal tube which is provided with a threaded portion $1, hall of which threads into the correspond ingly threaded portion of the mouth-piece T and the other half of which threads into the threaded portion 6 of the bowl stem 1.

The tube 8 extends beyond the threaded portion (5 and provided with an enlarged end 10 of substantially the same diameter as the orifice 2 and this enlarged portion is provided with a squared end 11 adapted to snugly abut the shoulder 3 in the pipe stem.

The metal stem 8 is cemented or otherwise rigidly secured in the mouth-piece T and the threaded portion 9 of the tube extending beyond the mouth-piece enters the threaded portion of the pipe stem or shank and secures the mouthpiece firmly in position and completes a passage from the bowl to the end of the mouth-piece having no lateral pockets in which moisture may collect.

The metallic stem is made in a very simple manner and accomplishes a very desirable condition in the pipe.

In the form illustrated in Figure 2 the metal stem 12 extends beyond the inner end of the mouthpiece and is provided with a threaded portion 13 adjacent to the cylindrical end portion 14. The threaded portion engages the inner threaded wall of the pipe stem and the end portion 1 1 is drawn tightly against the shoulder 3.

In the form illustrated in Figure 3 the metal stem 15 fits snugly in the bore 16 of the pipe stem and has an enlarged portion 17 which is preferably provided with a tupered end 18. This enlarged portion fits into the outer end of the stem of the bowl. This particular form may be made very economically by having. the portion 17 made in the form of a ferrule to slip over the reduced threaded end 19 which threads into the mouth-piece 20 and is permanently cemcnted therein.

In Figure 4: a structure very similar to that shown in Figure 3 is shown but the tubular stem 21 has an enlarged inner end portion 22 which abuts a gasket or washer 23 of a soft material, such as cork or leather and forms therewith a n'ioisture tight joint.

The tube 21 is provided with a threaded portion 9A which is screwed into the mouthpiece 25.

A pipe such as described may be kept very clean and in a sanitary condition as the inner stem abuts tightly against the shoulder in the bowl shank and said shoulder is very close to the interior wall of the bowl. Leakage of vapor or moisture around the end or the metal tube 8 is prevented by the tight joint at the shoulder 3 and hence the shank of the bowl is kept dry and accumulation of the filth therein is prevented. In ordinary pipes, due to the absorbent nature of the wood, the shanks of the bowls become saturated to such an extent that it is impossible to cleanse them, generally rendering them unfit for use, while one of my pipes may be used and enjoyed indefinitely.

V hat I claim as my invention is l. A tobacco pipe comprising a bowl having an integral shank or stem and a mouthpiece, the shank having an enlarged counterbore extending from its outer end entirely through the shank and terminating in a fiat annular shoulder close to the interior wall of the bowl and a short perforation connecting said counter-bore with the interior of the bowl, the mouthpiece having a longitudinal perforation and a counter-bore opening at its inner'end, and a tubular member pern'ianently secured in the counter-bore of the mouth-piece and fitted into the shank and having a squared end abutting and fitting said annular shoulder to prevent leakage when the parts are assembled, whereby a continuous passage without lateral pockets is formed leading from the interior of the bowl through the mouthpiece, and contan'iination ot the shank of the bowl is avoided.

2. A tobacco pipe com-prising a bowl having an integral shank or stem and a mouthpiece, the shank having an enlarged counter-bore extending from its outer end, entirely through the shank, and terminating in a flat annular shoulder close to the interior wall the bowl and a short perforation connecting said counter-bore with the interior of the bowl, the mouthpiece having a longitudinal perforation and a counterbore opening at its inner end, and a tubular member permanently secured in the counter-bore oi the mouthpiece and screw-threaded into the shank and having a squared end alnitting and fitting said annular shoulder to prevent leakage when the parts areasseinbled, whereby a continuous passage without lateral pockets is formed leading from the interior at the bowl through the mouthpiece, and contamination of the shank of the bowl is'avoided.
